I think campershell is the worst actually. There is no chance the air off of that does anything but swirl like the air coming off the back of a box truck. The bed cover gives a good chance the air coming off the cab lands and reattached before tumbling off the tailgate (a smaller box truck). The flatbed is probably to low to get the air to land. So aeroshell is best, flat bed cover next, regular open truck bed, tailgate up next, flatbed or tailgate down, and finally full camper shell the worst especially considering the added weight and cost.
